The trio of Dustin Johnson, Jordan Spieth and Martin Kaymer—the last three winners of golf's national championship—are grouped together for the first two rounds of the 2017 U.S. Open at Erin Hills, which begins next Thursday in Erin, Wis.

Johnson, the world's top-ranked player, will try to defend his 2016 U.S. Open title this year. He famously three-putted the 72nd hole at the 2015 U.S. Open at Chambers Bay to hand Spieth his second major championship.

Phil Mickelson has previously said he plans to skip this year's U.S. Open to attend his daughter's high school graduation, but he said he would wait until a couple of days before the tournament to withdraw. He's grouped with Steve Stricker and Stewart Cink for a 3:20 p.m. tee time Thursday.
